CAR-WHEE.L.

SPECIFICATION forming peri; of Letters Patent No. 356,855, dated February l, 18?.7.

Application filed May 17, 1886.

To @ZZ wwm it may concern.-

Be itknown that l', Encan Pncirii'nn, of Syracuse, in the county ot' Gnoiidaga, in the State oi'New York, haveinventednew and useful Improvements in GarWheels, oi'which the following, taken in connection with the ac coinpanying drawings, is a full, clear, and exact description.

This invention consists in a novel construction of a car-wheel which possesses maximum stability, and at the same time is cushioned so :is to protect its metallic parts from ing` nry to the grain of the metal and to the integrity of the wheel incident to the jars it is subjected to when in use.

The invention is fully illustrated in the annexed drnwings, wherein Figure l is a transverse section ot a Wheel embodying my improvements and teken on line x cc, Fie. 2. Figs. 2, 3, 4, and 5 are detached face views, respectively, of the Wheel-web, its hub, its cushion or lining, and detachable retaining collar; and Figs. 6 and 7 are transverse sect-ions of Wheels embodying modifications of my invention.

Similar letters of reference indicate corresponding parts.

A represents a car-axle of ordinary form.

B denotes the ivheethnb, which is composed of metal, and is rigidly attached to the axle either by pressing it thereon in the saine man# ner as ordinary canivheels are secured stationary on axles or in any other suitable and well-known manner. Said hub has on one of its ends, )referably the inner end, a collar, C, rigidly attached thereto or integral therewith, and thus also maintained slationaryin its position in relation to t-he axle. The opposite or outer end of the hub is provided with a cirenm ferential groove, D,the outer W all or shoulder of which is beveled, as shown in Fig. l of the drawings. In seid groove is seated removably the collar G, which has aeentral eye the same or nearly the saine diameter as the small diameter oi" the groove D, and has the outer face beveled around the end of the eye corresponding to the bevel of the groove.

In order to permit of seating the collar C in the groove D, I divide said collar diamet- Serinl No. 202,430. (No model.)

rieally and clamp the two sections together by bolts passing through ears b b on said sections, as illustrated in Fig. of the drawings.

F represents a metallic web of the wheel, and T the tread, which latter may be formed directly on the periphery of the aforesaid web, or consist of a tire secured to the web. This metallic web is secured between the two collars .C C by removing the outer collar, C', then slipping the web F by its central eye onto the hub, and bringing said web to rest against the inner collar, G, then placing the sections of the outer collar into the groove D, and tying said sections together by the bolt-s au. In the latter operation the collar-sections are drawn tightly into the groove D, and the beveled outer shoulder thereof crowds the collar toward the web F, so as to clamp the latter between the two collars C C'. This clamping of the web in its position I rcvcnforce by means of bolts I I, passing through holes N N provided in the two collars and intervening web, and by nuts on the ends ol said bolts.

The central eye of the web F, I make of a sufficiently greater dianifi-ter than the portion of the hub which it surrounds, to permit of inserting between them a cushion or lining, L, of paper, wood, or other suitable iibrous material, which is pressed into tubular shape and inserted endwise between the eye of the web and hub, so as to be concentric with the axis of the wheel.

The internal and external diameters of the cushion L correspond, respectively, to the diameters of the hub and of the eye of the web F, so that when pressed into its requisite position it tits as closely as possible to said parts and forms an eye of fibrous material in the metallic web of the Wheel.

In order to more eectually insure the close fitting of the cushion to the hub and to the eye oi' the web, I taper said parts longitudinally. Thetaperofthe hub is outward, and the taper of the eye ofthe web may be eitherinward, as represented in Fig. l of the drawings, or outward, as shown in Fig. 6 of the drawings, and the taper oi the cushion L is to be made correspondingly. ill/Then tapered, as shown in Fig. l of the drawings, the cushion L is to be inserted in the eye ofthe web F before applying the latter to the linb, and the cushion may be pressed and formed in the said eye to be rlgidly secured thereto, and thus wheel webs formed with fibrous or cushioned eyes may be furnished to the trade ready to be applied to axles equipped with hubs B.

The web, with its cushion L, can be pressed onto the hub by means of va wheel-press similar to those now employed for pressing carwheels onto axles, or by other suitable appliances.

Vhen the aforesaid parts are tapered, as

- shown in Fig. 6 of the drawings, the cushion may be first pressed onto the hub and then the web pressed onto the cushion.

The metallic eye of the web may be formed square or Octagon or other polygonal shape in cross-section, or may be provided with mortises or indentations in its interior, it desired, to more eiiiectually lock the cushion therein.

By placing a lining, it, ot' paper or analogous material between the sides of the web F and adjacent sides of the two collars G G, I obtain perfect bearings between said .parts without the necessity of planing or otherwise, cutting and fitting the surfaces thereof.

To prevent the web F from turningon the hub without subjecting the bolts I I to shearing strain, I provide the outer face of the rigid collar C and adjacent side of the web F with interlocking projections or lugs c c and corre* spending indentations or mortises, d d, the engagement of which parts compels the hub to rotate with the web and relieves the bolts I I of the shearing strain.

The bolt-holes through the web should be made large enough to leave spaces around the bolts, and, if desired, rubber sleeves may be slipped onto the bolts. F,l prefer to provide with annular projections or shoulders e e, which overlap the edges of the collars C C', so as to form supplemental bearings between the web and hub; and, if desired, a suitable liniug,f, may be applied to said bearings.

I do not Wish to confine myself to the employment of the hub B, inasmuch as the cushion or lining L may be applied directly to the axle A, as represented in Fig. 7 of the drawings; but in either case I employ the rigid collar O and removable collar C at opposite sides of the web F, and lock the web on the rigid collar by interlocking projections and indentations on the adjacent sides of said parts.

Having described n1yinvention,whatI claim as new, and desire to secure by Letters Patent, is-

1. In combination with the axle, a metallic hub formed with an axial bearing in one piece, a cushion encompassing said hub, a metallic web mounted on said cushion, a collar on one end of the hub and a collar detachably con- The sides of the web nected to the opposite end of the hub, and bolts for securing the detachable collar on the hub, substantially as set forth.

2. Inacar\vheel,the combination ofa metallic hub and a metallic web, and a cushion taperedlongitudinally and inserted eudwise into the space between the eye of the web and the hub, substantially as set forth.

3. In a car-wheel,the combination ofa metallic hub, a cushion encircling said hub, a rigid collar on the end of said hub, a metallic web seated on said cushion, and the adjacent sides of said collar and Web formed with interloclc ing projections andindentations, substantially as and for the purpose set forth.

4. In a car-wheel, the combination ofa metallic hub, a rigid collar on one end of said hub, a collar detaehably connected to the opposite end ofthe hub, a cushion encircling the said hub between the collars, a metallic web seated on the cushion, interlocking projections and indentations on the adjacent sides ofthe rigid collar and web, and bolts for clamping the detachable collar on the web, all constructed and combined substantially as set forth.

5. In a car-wheel, the combination of ahub, collars secured to opposite ends of said hub, and a web secured between said collars and provided on its sides with shoulders projecting over the edges of the collars, substantially as described and shown.

6. In a car-wheel, the combination ofa metallic hub, collars secured to opposite ends ofsaid hub, a cushion encircling the hub between the collars, and a metallicweb seated on said cushion and provided on its sides with shoulders projecting over the edges of the collars, substantially as described and shown.

7. In a car-Wheel, the combination ofa metallic hub, a rigid collar on the inner end of said hub provided with projections on its outer face, a circumferential groove in the outer end of the hub and having its shoulder beveled, a diametrically divided collar having an eye corresponding to the aforesaid groove, a cushion encircling the hub between thetwo collars, a metallic web seated on said cushion and pro vided at the side adjacent to the rigid collar with recesses corresponding to the projections of said collar, and clamping bolts passing through the two collars and intervening web, all constructed and combined substantially in the manner specified and shown.

In testimony whereof Ihave hereunto signed my name and affixed my seal, in the presence of two attesting Witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 13th day of May, 1886.
